Area Forecast Discussion National Weather Service Paducah KY 1253 PM CDT Sun Jul 12 2020 .UPDATE... Issued at 1253 PM CDT Sun Jul 12 2020 Updated aviation section for 18z taf issuance && .SHORT TERM...(Today through Tuesday night) Issued at 230 AM CDT Sun Jul 12 2020 Quite an impressive cluster of thunderstorms developed over the Pennyrile region of west Kentucky after midnight. The kpah radar observed a 60 dbz core above 40k feet in White County, IL earlier. Strong radar indications of large hail have not translated into sfc reports as yet, but the storms have been over rural areas thus far. The 00z cams (convection-allowing models) have done a very good job with the storms over the Pennyrile region of KY so far. These storms may continue to pose an isolated large hail threat into the early morning hours. A rather impressive 500 mb shortwave and its associated jet streak will continue to induce more convection ahead of a surface cold front today. The cold front will cross the Ohio River by 18z. The front will cross the Pennyrile region of west KY and southwest Indiana this afternoon, where the cam models indicate storms may again pulse up as daytime heating peaks. A few severe cells cannot be ruled out. The front will exit our region by 00z, followed by dry weather tonight. Highs today will be limited to the mid 80s where storms are more likely in the Pennyrile region of west KY and sw Indiana. Areas of se Missouri will reach close to 90. Weak high pressure will result in lots of clear sky, lower humidity, and somewhat lower temps tonight through Monday night. Overnight lows will be mainly in the mid 60s. Daytime highs will be in the mid to upper 80s Monday, maybe reaching 90 in se Missouri. Return flow on the back side of the high pressure system will kick in on Tuesday. Highs will be in the lower 90s. Dew points will only slowly creep up toward 70 Tuesday night, especially over se Missouri. Along with the arrival of the more tropical air, there will be a slight chance of showers or storms late Tues night in srn IL and se MO. .LONG TERM...(Wednesday through Saturday) Issued at 230 AM CDT Sun Jul 12 2020 Models continue to trend wetter for next week. The region stays in more of a northwest flow for the week with only weak periodic ridging from the southwest. This will allow for weak troughs to pass near/across the area. The better chances for showers and storms appears to be Wednesday night into Thursday and again on Friday. After Friday, the ridging does start to work northeast reducing rain chances to mainly diurnal pop up afternoon/evening storms. Any kind of surface boundary stays well to our north through the period. An increase in the chances for precipitation should help tone down the heat next week. Models now show highs in the lower to middle 90s. Combined with dewpoints in the middle 70s, we should see heat indices between 100 and 105. && .AVIATION... Issued at 1253 PM CDT Sun Jul 12 2020 Thunderstorm impacting KEVV at 1730-1750Z with G20KT and 1/4 vsby with +TSRA. This group of thunderstorms will impact KOWB by 1830Z with similar impacts likely. Otherwise will maintain VCTS at these 2 sites til mid to late afternoon with other thunderstorms possible. VFR conditions at other TAf sites and by late afternoon VFR conditions will prevail at KEVV and KOWB through the TAF periods with Northerly winds of 5-10 knots. && .PAH WATCHES/WARNINGS/ADVISORIES...
